## Description

r128 is an XFree86 driver for ATI Rage 128 based video cards. It contains full support for 8, 15, 16 and 24 bit pixel depths, hardware acceleration of drawing primitives, hardware cursor, video modes up to 1800x1440 @ 70Hz, doublescan modes (e.g., 320x200 and 320x240), gamma correction at all pixel depths, a fully programming dot clock and robust text mode restoration for VT switching.

## Supported Hardware

The r128 driver supports all ATI Rage 128 based video cards including the Rage Fury AGP 32MB, the XPERT 128 AGP 16MB and the XPERT 99 AGP 8MB.

## Configuration Details

Please refer to XF86Config(5) for general configuration details. This section only covers configuration details specific to this driver.

The driver auto-detects all device information necessary to initialize the card. However, if you have problems with auto-detection, you can specify:

> VideoRam - in kilobytes
> MemBase - physical address of the linear framebuffer
> IOBase - physical address of the MMIO registers
> ChipID - PCI DEVICE ID

In addition, the following driver Options are supported:

Option "SWcursor" "boolean"
  Selects software cursor. The default is off.
Option "NoAccel" "boolean"
  Enables or disables all hardware acceleration. The default is to enable hardware acceleration.
Option "Dac6Bit" "boolean"
  Enables or disables the use of 6 bits per color component when in 8 bpp mode (emulates VGA mode). By default, all 8 bits per color component are used. The default is off.
